Problems solved by technology

The turbulent flow mechanically stirred molten iron tank plays a significant role in improving the desulfurization dynamics by setting several inner flanges on the inner wall of the molten iron tank, but the inner flanges set on the inner wall of the molten iron tank will not only affect the lining of the molten iron tank It will have an impact, and will cause the desulfurization agent to accumulate at the inner flange, forming a new weak flow area

Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] The flow control device in a KR desulfurization molten iron tank provided by the present invention is as follows: Figure 2-4 As shown, it is the same as the prior art in that it also includes a stirring device 2 inserted into the molten iron tank 1. The stirring device 2 is composed of a stirring head 5 and a stirring rod 6. The difference is that it also includes a bracket 3 and a stop rod 4. The bracket 3 is installed above the molten iron tank 1. The baffle rod 4 has several strips. The upper ends are distributed and fixedly installed on the bracket 3, and the lower ends are respectively inserted into the molten iron tank 1, and are distributed symmetrically with the stirring rod as the axis.

[0026] As an example, the baffle rod 4 can be made of refractory material, and of course, the baffle rod 4 can also be coat...

Abstract

The invention discloses a flow control device in a kambara reactor (KR) desulfuration molten iron tank. The flow control device comprises a stirring device inserted into the molten iron tank, and the stirring device is composed of a stirring head and a stirring rod. The flow control device further comprises a support and a plurality of stop levers. The support is arranged above the molten iron tank, the upper ends of the stop levers are fixedly arranged on the support, the lower ends of the stop levers are inserted into the molten iron tank, and the stop levers are symmetrically distributed with the stirring rod as an axis. A periodic effect is generated on a stirring flow field of the molten iron tank through the stop levers, formation of a center eddy region is remarkably restrained, the desulfuration dynamic condition of molten iron mechanical stirring is obviously improved, and the utilization rate of a desulfurizing agent is greatly increased.

Description

technical field [0001] The invention relates to a KR stirring desulfurization hot metal tank outside a molten iron furnace, and more specifically relates to a flow control device in the KR desulfurization hot metal tank. Background technique [0002] KR (Kambara Reactor) stirring desulfurization method is a desulfurization technology outside the molten iron furnace that was applied in industrial production in 1965. This desulfurization method is mainly to insert the stirring head into a molten iron tank with a certain depth to rotate, and the vortex generated by the rotation drives the movement of the desulfurizer and reacts with the molten iron, so as to achieve the purpose of desulfurization. Compared with the injection method, the KR method has obvious advantages in deep desulfurization and desulfurization stability, so it has been widely used at home and abroad. However, there are still some shortcomings in the actual production of the KR method, such as the low utiliza...
